Outputs  an  image  of  a form as it would appear when displayed. The
  argument  specifies  the  type  of  output device.  The  legal values
  are  NOESCAPE_SEQUENCE,  ESCAPE_SEQUENCE,  VT100_ESCAPE_SEQUENCE  and
  LN03_ESCAPE_SEQUENCE. NOESCAPE_SEQUENCE, the default, produces output
  for  ordinary  printers.  ESCAPE_SEQUENCE produces output for devices
  that  support  VT100  ANSI  Escape Sequences.   VT100_ESCAPE_SEQUENCE
  produces output for devices that support VT100 ANSI Escape Sequences.
  LN03_ESCAPE_SEQUENCE produces output for  devices  that support  LN03
  Escape Sequences. The default input file type is FRM, and the default
  output file type is LIS.

  FMS/DESCRIPTION/DISPLAY_IMAGE replaces FMS/DESCRIPTION/IMAGE.

  Example:  FMS/DESCRIPTION/DISPLAY_IMAGE=ESCAPE_SEQUENCE FORMLIB1-
                                                            /FORM=FORM1

      The output image file will contain escape sequences so that when
      the  form  is displayed on a VT100 or VT100 compatible terminal,
      the video attributes can be seen as defined.
